External clock AD trigger
3.1.2.
In this trigger, send a start command from PC over the Ethernet to PET-7H16M to start the
acquisition. The A/D conversion is started actually when the external clock signal is input. The AI
value converted to digital data followed the external clock sampling rate and the data
accumulated to a network packet size returns to the PC. The process is stopped until a stop
command is sent over the Ethernet.
The frequency of the external clock can range from 1~30K Hz.
